Design and Characterization of a Silk-Fibroin-Based Drug Delivery Platform Using Naproxen as a Model Drug
Figure 1
Purification of SF solution (7.2%) by Sephadex G-25 (medium grade) column chromatography using gravity flow. Elution of SF (–▲–) and CaCl2 (–■–) salt is shown as net dry mass recovered in each fraction collected, and both are confirmed by UV absorbance at 280 nm and conductivity measurements, respectively.
